Excerpt from Soils and Crops of the FarmPlants live and grow. Growth comes from food. Plant food must come from, or through, the soil or air, or both. Plants cannot move about to seek food. They do not have mouths like those of animals. They cannot take in solid substances. Their food must be brought into contact with them and be either liquid or gaseous in form.Finding out of what a plant is composed will help to an understanding of how and from whence it gets its food.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
